4 lane dual carriageways

[ldriver]

What examples are there of 4 lane each side (8 total) Dual carriageways? I think i've seen a term like D4 used around here to describe them I've seen pictures of one but can't seem to locate any on google maps etc.

[Mark Hewitt]

This is one http://goo.gl/maps/QuXmr sure many of the lanes are for turning off etc, but the cross section is D4.

Street View is a little behind the times, but isn't this a D4?

Plenty on the motorway network, such as the A1(M) between Alconbury and Peterborough. The A2 in North Kent is a good non-motorway example. I know it looks like a motorway, but it isn't.

But that's a D4M isn't it not?

Here's a long-standing D5 on the A406 North Circular Road in Woodford, east London

i'm assuming we're excluding Motorways from this then?

The A27 between the A2030 and A3(M) is D4 (and with hard shoulders too!) http://goo.gl/maps/i0aRl

The A31/A338 multiplex (about a mile long) is D4

I'm really struggling to think of any others in the South East that haven't already been mentioned.

I assume you meant the M1 example. The A2 certainly looks like a motorway but isn't one. It's always been high quality. Going back to building in the seventies there were three lanes along there and then two for the M2.

There's probably loads in urban areas on the approaches to traffic lights! So length might need to be another criteria!

No I meant the A2 example. It has 4 running lanes plus hard shoulder which makes it D4M.

cbrd.co.uk : "D3M is a dual carriageway with three lanes each way and is equipped with full hard shoulders. The 'M' refers to the fact that this is a motorway formation, but a non-motorway road equipped with full hard shoulders is described this way too (i.e. it is an engineering term, not a legal one)."

Duly noted and out-pedanted.

Part of the A494 is technically D4M, although in the eastbound direction one of the lanes becomes a lane drop, and in the westbound direction, the extra lane was never opened and the hard shoulder is extra-wide as a result.

The road was to continue as D4M over the bridge (or D3+4M, possibly), but the cancellation of Drome to Ewloe in 2008 means this will probably not be completed any time soon.

A5103 is D4 between the M56/A560 and M60 J5, except that it is D3+HS within the junction with the B5166/7.

I can confirm it is a D4, since I live about 1 mile (if that) away

The roadworks are the Sadlers Farm Roundabout improvement works that involved a widening of the A13 from D2 to D4 and were completed not that long ago
Hope I helped

The A52 Clifton Bridge here is 4 lanes in each direction, though it's a sort of D3+1/D4 layout.

D4 it is!

[Sunil_of_Yoxley]

Another D4 section on the A13:



And there's another section in Rainham.

[SuperCoolAl]

M62 J25-26 is now D4. No hard shoulder.

[hoagy_ytfc]

D4 it is!

If that's D4, then so is the A34 for a stretch south of the junction with the M4.

No idea if this is an 'official' term, but I'd call it D2+2 or something like that. It's not really four lanes each way, it's two pairs of two.
